2018 HYUNDAI SONATA Complaints

CAR WILL NOT START WHEN KEY TURNED IN IGNITION WITH NO SOUND WHEN THE WEATHER IS UNDER 30 DEGREES. HAD IT IN THE DEALER LAST WEEK AND THEY COULD NOT FIND THE PROBLEM. STILL HAPPENING SO ITS BACK IN THE DEALER FOR 3 CONSECUTIVE DAYS AND I CANNOT TALK WITH ANYONE IN THE SERVICE DEPARTMENT. PHONE JUST RINGS THEN CUTS OFF. HAVE DONE RESEARCH AND FOUND OTHER 2018 SONATA ES OWNERS WITH THE SAME PROBLEM AND THE SOLUTION HAS BEEN THE IGNITION STARTER AND SOLENOID. WHEN REPLACED THE STARTING PROBLEM WAS SOLVED. THREE DAYS NOW AND HAVE NOT HEARD FORM THE HYUNDAI REPAIR SHOP IN BOWIE, MD. STILL HAVE MY CAR. SUCH INEFFICIENTLY WITH MECHANICS NOW DAYS.

I WAS I A PARKING AND I OPENED THE TRUNK, AFTER THAT IT WAS IMPOSSIBLE TO CLOSE IT. THE TRUNCK LATCH FAILED. IT HAS A PLASTIC PART THAT BROKE. I HAD TO PURCHASE A NEW ONE.

WHILE DRIVING CAR ON AN INTERSTATE HIGHWAY ENGINE POWER SUDDENLY DECLINED AND VEHICLE HAD NO PICKUP. I WAS UNABLE TO KEEP UP WITH THE HIGHWAY TRAFFIC, I HAD TO TOW THE CAR TO THE DEALERSHIP FOR REPAIRS. I WAS INFORMED BY THE HYUNDAI SERVICE DEPARTMENT THAT MY CAR REQUIRED A COMPUTER SOFTWARE UPGRADE TO CORRECT THE CONDITION. APPARENTLY THEY ARE AWARE OF THIS PROBLEM BUT THERE ARE NO RECALLS CONCERNING THIS PROBLEM.

I WAS DRIVING IN ANOTHER CITY AND MY CAR WENT INTO LIMP MODE. I HAD IT TOWED TO NEARBY DEALER AND THEY SAID I WAS LOW IN OIL, AFTER HAVING IT CHANGED AN MONTH BEFORE. THEY DID OIL CONSUMPTION TEST AND FOUND IT TO BE 1 QUART PER 1000 MILES AND LEFT THERE AND 2 MONTHS LATER HAD ANOTHER CONSUMPTION TEST DONE AFTER SEEING MY CAR WAS ONE IN THE CLASS ACTION ON ENGINE AND BEARINGS. THEY FOUND THIS ONE TO BE 1.1 QTS PER 1000 MILES. DEALER SAID NO WAY WILL THEY SEND INFO TO GET A NEW ENGINE UNDER WARRANTY. A QT A 1000 MILES SEEMS VERY EXCESSIVE. DEALER SAID THAT YOU NEED TO BE AT 1.5 QT PER 1000 WHICH WOULD BE ALMOST NO OIL WHEN I GO HAVE AN OIL CHANGE. THE VEHICLE IS ONLY 3 YEARS OLD AND 100000 MILES. THIS SEEMS LIKE TOO MUCH OIL TO BE BURNT. AND THEY KNOW THEY HAVE ENGINE ISSUES AND WILL NOT RECTIFY

WHEN ACCELERATING FROM A STOPPED POSITION THE VEHICLE SHUDDERS OR STUTTERS BEFORE PROPER ACCELERATION IS ACHIEVED. I OWNED A FORD FIESTA THAT DID THE SAME THING AND IT TURNED OUT TO BE THE CLUTCH. IS THAT A POSSIBILITY WITH MY SONATA?

IN FEB 2020 MY SONATA WENT INTO SAFE MODE AFTER EXITING HIGHWAY AND DEALER ENDED UP REPLACING "KNOCK SENSOR". IN DECEMBER 2020 MY ENGINE "STUTTERED" THROWING ME FORWARD AS IF I HAD HIT BRAKES HARD. NO WARNING LIGHTS OR MESSAGES OCCURRED AND AFTER A FEW SECONDS CAR ACTED NORMALLY MOSTLY. A FEW DAYS LATER AFTER EXITING HIGHWAY AGAIN THE ENGINE WARNING LIGHT (ORANGE) CAME ON ALONG WITH ERROR MESSAGE "POSSIBLE CONDITION WITH ENGINE CONTROL SYSTEM" HAS BEEN DETECTED. CAR DID NOT GO INTO "SAFE MODE" AND SEEMED TO BE OPERATING NORMALLY. I CONTACTED DEALER WHO ASSURED ME SAFE TO DRIVE OVER HUNDRED MILES BACK TO DEALERSHIP IN THIS CONDITION TO CHECK. I DROVE BACK FROM EAST COAST FL TO WEST COAST FL TO TURN CAR IN. I BELIEVE ENGINE ISSUE EXPERIENCED IS RELATED TO THE THETA ENGINE ISSUE AND REPAIR WOULD BE COVERED UNDER SETTLEMENT. DEALERSHIP DISAGREES AND HAS INDICATED ISSUE IS WITH FUEL PUMPS (BOTH ARE BEING REPLACED) AND CHARGING ME $2300.

DRIVING NORTH ON INTERSTATE 530 IN ARKANSAS, ABOUT 40 MILES SOUTH OF CLINTON LIBRARY THERE WAS A SUDDEN EXPLOSION OF GLASS FROM THE SUNROOF. THE INTERNAL VISOR WAS OPEN AND GLASS BEGAN TO POUR INTO MY LAP, SHIRT AND THE OTHER SEATS IN THE VEHICLE. I SCREAMED IN FEAR AND PULLED OVER TO THE SIDE OF THE ROAD. THERE WERE NO OTHER VEHICLES IN FRONT OF OR BEHIND ME AT THE TIME.

TRUNK LATCH LOCKING ARM CAN BREAK WITH FEW MILES ON THE ODOMETER. WHEN THE ARM BREAKS DUE TO IT BEING PLASTIC CONNECTING TO METAL VIA A STRONG TENSION SPRING, THE EMERGENCY TRUNK RELEASE LEVER IS DEFEATED AND THE TRUNK CANNOT BE OPENED, OR CLOSED IF IT BROKE WHILE OPEN.

I TURNED ON MY CAR AND THE MALFUNCTION INDICATOR LIGHT TURNED ON MY DASH BOARD. I PUT THE CAR IN REVERSE AND IGNORED IT. KEPT DRIVING. THE CAR TURNED OFF COMPLETELY WHEN I WAS TURNINGIN IN A BUSY INTERSECTION. I TURNED IT ON AGAIN AND IT DIDN'T WANT TO EXCELERATE.

HEADLIGHT LENS HAS A PROJECTION IN THE MIDDLE OF THE LENS THAT INTERFERES WITH AND IS VERY DISTRACTING TO THE LIGHTED FIELD OF VISION. HYUNDAI MECHANICS HAVE TIOLD ME THEY'VE GOTTEN MANY COMPLAINTS FROM DRIVERS, BUT HYUNDAI REFUSES TO CORRECT IT. I FILED A FORMAL COMPLAINT WITH HYUNDAI, AND THEY GAVE A VERY DUBIOUS AND WEAK EXCUSE FOR THE DEFECT. THEY RESPONDED IN WRITING TO ME "THE BLACK HALF-MOON TRIANGULAR IMAGE IS DESIGNED TO PREVENT GLARE TO THE VEHICLE TRAVELING IN THE OPPOSITE DIRECTION. HYUNDAI MOTOR AMERICA IS UNABLE TO REPLACE THE HEADLAMP ASSEMBLY FOR CONCERNS RELATED TO THE HALF-MOON/TRIANGULAR SHADOW." THIS RESPONSE DEFIES LOGIC AND IT APPEARS TO BE AN AFTER THE FACT FABRICATED RESPONSE SO THAT THEY DON'T HAVE TO CORRECT THE DESIGN FLAW. THIS FLAW IS OBVIOUSLY ONLY OBSERVABLE DURING NIGHT DRIVING.
